Thank you for the message. I have asked one of our PMs to reach out directly to you -> investigate this and report issues if such exist. This is with what we begin with - then, if required, fixes will be done.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
